The concrete tower was inaugurated on December 17, 1991, is the highest point in Curitiba with its 109 meters height. It is located at Merces Disctrict.
At the top of the tower there is an observation deck that allows a 360 degrees view of the city. It belongs to a telecommunications company and that is why you will find a museum about this subject at the bottom of the tower. It is really cheap to access the tower (less than one dollar).
I have taken a lot of pictures from up there and in a near future I wil post a series about it.
